Jessica Simpson had a close shave

Jessica Simpson walked in a Herrera gown showing off her fabulous body after weight loss on the red carpet, accompanied by her fiancÚ Eric Johnson who was in Ralph Lauren. "It's definitely chaotic," she told USA Today of the big event, "and I should not be wearing a train on my dress. I don't know what Ms. Herrera's going to say when I get it back to her."

However at the after party, she risked a near-nip slip in a very low-cut black dress with a high slit. She uploaded a picture in the dress on Instagram and captioned it, "After the prez it's the after party."

Ten years ago, her father Joe Simpson told GQ, "Jessica never tries to be sexy. She just is sexy. If you put her in a T-shirt or you put her in a bustier, she's sexy in both. She's got double D's! You can't cover those suckers up!"

Simpson and Johnson were out sans their babies Maxwell,2 and Ace, 10 months and seemed thrilled about the fact. "It's me and Eric's first date night!" Simpson told USA Today.

The "I Wanna Love You Forever" singer, 33, gave away details about her prolonged wedding. "We are very close to sending out our invites," said the star, who was previously married to Nick Lachey from 2002 to 2006. "Eric's family alone is almost 90 people, so it'll definitely be a big event."

"We're building a studio in our house. I bought a house from Ozzy Osbourne so a lot of the studio was already set up," the blond beauty said. "I want to see what comes out. It's time for me to find that out, and I can't wait for my kids to experience that with me. Even Eric. He's never seen me perform onstage."
